The discovery was made by a gamer going by the name of Trike on the NeoGAF forums. All he did was hover over the exit button of Miiverse and pressed the “X” button on the GamePad. He was then presented with a prototype Miiverse in Japanese, could see lists of admin accounts, regenerate passwords, view other gamer’s (and developer’s) private messages, and had the option to delete accounts. He did none of those things because he didn’t want to get his Wii U banned.

It didn’t take long for news of the debug menu to spread across the Internet, and Nintendo reacted by releasing a patch that closed off access. Trike apparently received a PM from a developer at Nintendo stating he may be facing some legal action. I doubt that though, as all he did was access functionality available on the console without modifying his machine. He did nothing wrong, it was Nintendo who made a mistake.

Accessing the debug menu may have caused Nintendo a few headaches yesterday, but it also revealed two new Wii U games via a developer message and link. Apparently on December 10 Nintendo is set to announce Yoshi’s Land Wii U and Soul Hackers. The content of the first game should be obvious, but the second one is an unknown. The best guess at the moment is that it’s a follow-on series for Konami’s Metal Gear Solid, which would be a major draw for gamers and a clever move by Nintendo if it’s exclusive to the Wii U.
